Okay, this is the first game so far that I really enjoyed. Both concept and execution were GREAT.
I love the fact that you can shoot yourself with the gun. I love the fact that the gun recoils when fired. I even love the fact that the game's premise makes no sense (aliens in a western setting?).
The game in its entirety is just plain fun and I'm 100% on board with it. This is a strong contender.
